It grows well in regions with daytime temperatures between 65-75°F (18-24°C) and nighttime temperatures around 50°F (10°C). The plant can also tolerate frost but not extreme heat. It is commonly grown as an annual in regions with hot summers.
Soil Requirements
Diascia jonantha Dinter grows best in a well-draining, fertile soil rich in organic matter. A slightly acidic to neutral pH range of 5.5-7.0 is ideal for the plant's growth. The soil should also be moist but not waterlogged. You can amend the soil with compost or well-aged manure to improve its texture and fertility. The plant does not tolerate compacted or heavy soils, which can inhibit root growth, leading to stunted plants.
Cultivation Methods
The Diascia jonantha Dinter plant thrives best in sunny locations and well-drained soils that are rich in organic matter. It should be planted after the last frost, which is typically in late spring or early summer. While it prefers full sun, it can also grow in partial shade, but it will not flower as abundantly.
Watering Needs
Watering the Diascia jonantha Dinter plant is important as it does not tolerate drought well. It requires regular watering, especially during the hot summer months. The plant needs to be watered deeply, but it should not be waterlogged. Overwatering can cause root rot and other problems.
Fertilization
The Diascia jonantha Dinter plant requires regular fertilization to ensure that it grows healthy and produces an abundance of flowers. A balanced fertilizer that has high amounts of phosphorus is ideal. The fertilizer should be applied at least once a month during the growing season.
Pruning
Pruning is necessary to keep the Diascia jonantha Dinter plant looking neat and tidy. Deadheading the plant removes spent flowers and encourages it to produce more blooms. Pinching back the tips of the plant can also encourage bushy growth and branching. Pruning should be done in the early spring before new growth begins.
Propagation of Diascia jonantha Dinter
Diascia jonantha Dinter, also known as the Twin Spur, is a plant that produces attractive pink and white flowers. Propagating this plant can be done using several methods which include:
Softwood cuttings propagation
With softwood cutting propagation, you will need to start it in late spring or early summer when the plant is actively growing. Take semi-ripe cuttings of about 3-4 inches long, remove the lower leaves and dip the cut end into rooting hormone powder. Place the cuttings into well-draining soil mix and cover with a clear plastic bag to retain moisture. Keep the cuttings moist and out of direct sunlight, and once roots have formed, you can transplant them into individual pots and place them in a bright spot.
Seeds propagation
You can start Diascia jonantha Dinter from seeds, either in the spring or fall. Collect the seeds when the flowers have faded and turned brown, and plant them in a well-draining soil mix. Cover the seeds lightly with soil and water them well. Place the tray or container in a bright, warm location and keep the soil moist. The seeds should germinate within 7-21 days, and once the seedlings are large enough, transplant them into individual pots or directly outside in the garden.
Division propagation
This method involves dividing mature plants and it is best done in the spring or fall. Carefully dig up the plant and separate the clumps into smaller sections with roots attached. Replant the divided sections in well-draining soil and water them well. Keep the newly transplanted areas moist and out of direct sunlight until they establish and start growing again.
Once you have successfully propagated Diascia jonantha Dinter, you can enjoy its beautiful flowers for years to come.

Pest Management
Although Diascia jonantha Dinter is relatively resistant to pests, they can still be a problem for this plant. Aphids, spider mites, and whiteflies are the most common pests that can infect this plant. Aphids suck the sap from the plant's leaves and flowers, causing them to wither and die. Spider mites can cause a lot of damage in a short time, as they feed on the plant's leaves, damaging their tissue. Whiteflies are tiny insects that cause yellowing of the leaves and can transmit diseases.
Disease Management
The best way to manage fungal infections in Diascia jonantha Dinter is to ensure adequate ventilation and air circulation. You can also use fungicides to treat and prevent further spread of the disease. For powdery mildew, you can use a solution of water and baking soda, sprayed onto the affected areas. For rust, you can use a copper-based fungicide. Additionally, you should remove any infected parts of the plant and dispose of them properly.
Pest Control
The best way to control pests in Diascia jonantha Dinter is to maintain the plant's overall health. Ensure the plant is not stressed so that it can resist pest attacks. Additionally, you can use insecticidal soaps, neem oil, or other insecticides to control aphids and spider mites. Whiteflies can be trapped with yellow sticky cards or removed by washing the leaves with water and soap. Handpicking the pests manually can also be an effective way to control their population.
By following the above-mentioned disease and pest management practices, you can effectively protect and maintain the health of your Diascia jonantha Dinter plant, helping it to thrive and produce beautiful blooms throughout the season.
